The mechanism for holding` and ln'esentin'gl the t buckles and tngus'iu properpositiouto be united lli by the upsetting and bending-tools, consists of a horizimtal` circular head-block, 'r,' having a cylindrical shank or stein, It, which passes through an opening in the bed-plate, and by which it is secured thereto.

-n-o- Y IMPROVE!) MACHINE FOB. MAKING- BUCKLES The Schedule lreferrer?. to `in these Letters` Patent and making -pim: of tho same ends ofthe tongues 3 in position, also serves a seat furthe inner sides of the buckles, while the outer bar ot the buckle rests upon the fiat-tened curved end of thetongues, which rest upon au annular recess, 6, adjacent to the circumference of said head-block; and in order to maintain the buckles in proper position upon thetongues 3, I lsecure a horizontal disk or plate, 7, upon the concentric shoulder 5, so that its circumference 'overlaps the seat of the concentric shoulder, in such manner as to leave an annular space, 8, between the two, equal to the thickness of' the ends of the buckles, so that when the latter nre inserted within the annular groove 8, they will tit tightly therein, aml be clamped and held in position during the rotation of the head-block r, as shown in figs. 7 Vand 8.

The holding-disk 7, is secured-to the head-block r, by means of `a central screw, 9. n Y This intermittentlyrevolviug head-block r, is lo cated so that its circumference will be flush with the end of the bed-plate upon which it is supported; and immediately in the rear thereof, and in aline with the ccntreof the bed-plate, I arrange, a bending-tool, 'ci-2,

figs. 1, 4, 7, and `8, so that its acting-end will be4 contongue 3, already upset, so as to 'complete the operation ottinrming the eye of the tongue over the bar of' the buckle.

This vertically-reciprocating tool q, is secured to a' vertically-sliding carriage or cross-head, q2, moving in ways in a transverse frame, b','sup1mrted by standards erected ou the bed-plate.

The reciprocating tools thus arranged, are secured in openings in their respective cross-heads, by means of clamping-plates 1l), so that they may be adjusted `nearer `to or further from the interniittently-revolving head-block r', so as to make their movelnent such to etect the proper action nin bending and thrilling the eye of the tongue.

The acting-ends of the horizontally and verticallyreciprocating tools, are provided with cavities d? i, as shown in figs. 4 aml- S, ot' the proper shape to receive the end ot' the tongue', in upsetting kand bending the same.

'.Lhe reciproca-ting movement ot' the horizontal upsetting-tool a" is et'ected by means of a connectingrod, "c, united, by a joint, to the rear end of the hori- Zontal c1oss-l1ead'u,and connected at its opposite end, by an anti-friction roller, to a cam, j, of peculiar' shape, represented in fic. .1 of the drawings; and in,v order that the rear end'of this connecting-rod c may be held in a fixed position vertically, and at the same time allow it to move back and forth, it is connected by a slot, fig. l, within which is secured an anti-frict-ion roller, fu', secured in a stud, af, on the bed-plate.

The cross-head of' the vertically-reciprocating tool qi, is connected to and receives its motion fromawalking-beam, d, mounted in bearings in standards c, erected upon the bed-plate, int'crmediately between the said vertically-acting lfool q, and the cam j, from which it derives its motion.

The opposite end of thiswalking-beam is connected by a vertical link, j', the lower end of which carries an anti-friction roller, fitted -to move within the groove of a cam, ji, of peculiar shape, as shown in fig. 3 of the drawings, located and arranged upon the same axis of' the cam j, for operating the horizontal-tool.

1n order to maintain the vertical link in its propel' position to receive the action of the carnjl, and allowit to rise and fall, it is provided with a slot, g, to receive au anti-fliction roller, h, fixed upon the upper end of a curved arm, i, secured upon the bed-plate, so as to hold inposition against the action of the groove jl, figs. l and 5, whilst it is permitted to risc and fall freely.

In order to allow of the free movement of the vertical cross-head q2, it is connected, by a hinged or pivoted link, 11, to the front end of the walking-beam d,4 while the rear end of the latter is pivoted, by an adjustable box, e, to the vertical link j, and thus pel'- mits the several parts to operate without bindinff.

l The two cams, thus located and arranged, do not operate simultaneously, but give motion to theacting-A tools, so that the horizontal one, a?, shall first bend the end of the tongue, to be followed immediately by the descent of the other, q.

The intermittent motion of the horizontal-revolving head-block lr, to present, in regular succession, the buckles and tongues to the acting-tools, to have their parts united and carried out of the way, is effected by means'ot' a ratchet or toothed wheel, 12, as shown in Figures 1 and 9, secured on the end of the shank or stem It of the head-block c', directly beneath the bedplate; and a spring-toothed arm, t, is connected by incans of a stud, ti". 1, projecting through an opening in the bed-plate, from the under side of the crosshead u, of the horizontally-reciprocating upsetting-tool u?, so as to cause the said toothed-spring arm t, to move back and forth with it.

The teeth ofthe ratchet-wheel and the tooth of the .spring-arm are of such shape as that the springtoothed arm t, on its advance movement, will move over the teleth ofthe ratchet without turning it, while its receding movement will cause the two to bite into cach other, and thus turn the ratchet-wheel, and, with it, the head-block 'r.

rIhe stroke of' the horizontal cross-head, therefore, and the distance'betwcen the teeth of' the ratchetwheel 12, fig. 9, (which latter isla horizontal section ofthe toothed feeding-wheel and its operating-amm) and the spaces between the buckles of the revolving head-block fr, as shown in fig. 7 (which is a full-sized rcpresentatiom) must be so proportioned and regulated as that each vibration of the horizontal spl'ing-twthed arm t, will turn the circular' head-block r, a distance exactly equal to that between thc buckles thereon,

.and thus never fail to present the shank of thc tongue 3 in a line directly with that ofthc upsetting-tool ai.

As cach buckle is completed, it is carried out of the way bythe rotation ofthe head-block lr; and in order to detach it therefrom, to give place to a new tongue and buckle, I arrange, at that side of the head-block which carries the finished buckle from thc tools, a

spring-detaching arm, c', figs. 1, 2, and 5, connected by pivot to the ways of the cross-head of the horizontal upsetting-tool.

The acting-end of this detachcr c is in a line with the diameter of the revolving block r, at right angles vto the movement ofthe horizontal upsetting-tool, and

is provided with a hook, 13, whose function is to pass ovcrthe outer bar of' the buckle, so as to' lock itself therewith, to remove the finished buckle.

This .is accomplished by means of' a cam-shaped projection, ll', (sce iig. 5,) on the side of the crosshead, arranged in such manner, relatively to the springhook c', as that, upon the advance movement of the upsetting-tool, the cam will strike a shoulder, g', on the said spring-arm, and force it outward from the revolving head-block, and with it the buckle, which being held,-by the overlappingr disk 7, upon the headblock, needs only to be drawn out to be detached therefrom, and the receding movement ot' the upsettingtool will release its cam from the spring-arm, when the latter will be forced in again, to lock itself with the next finished buckle, by means ofa spring, a, (see tig. 2,) which constantly tends to press the dctacher c' toward the rotating head-block r.

In giving motion to the rotating head-block by means of the toothed spring-arm t and ratchet-wheel 12, it would be liable to be moved ai little too far, and thus carry the buckle-tongue out of line with the upsetting-tool. I

To prevent this,therefore, I attach a friction-spring, in any convenient manner, to the bed-plate, so as to constantly bear against the circumference of the rotating head-block lr, and thus act as a brake-to its motion, so that the tongue will always be presented in a line with the upsetting-tool, and also hold it in position while the spring-toothed arm tis moving over it, to lock itself with one ofthe teeth of the ratchet'12.

The .mechanism for giving motion to the several parts of the machine consists of a transverse shaft, n, located and fit-ted in bearings at the rear end of the bed-plate, carrying at one end a driving-pinion, m, which matches with a cog-wheel, I, on the end of the cam-shaft k; and on the opposite end of the transverse shaft n, is a pulley, 11, over which the band from the driving-power passes; and to give evenness to the motion of the several parts, a fiy or balance-wheel, o, is arranged on the end of the driving-shaft next the driving-pinion.

To throw the machine into and out of gear, I pivot a clutch-lever, y, to the side of' the bed-plate, so as to lock and unlock the band-wheel, with aclutch, el, on the drivilnf-shaft, in the ordinary manner.

The operation of' the machine is as follows:

'lhe operator seats himself in. front'of the machine;

places a number of' tongues and buckle-frames upon the face of the rotating head-block. The clutch is then thrown into gear with the driving-band wheel p, which puts the machine in motion; and each revolution of the cam j causes the horizontal tool a to advance, and upset the e'nd of the tongue 3, which is held rigidly npon the rotating horizontal head-block r, so that its end projects beyond the circumference thereof, and as it cannot yield, will receive a sharp curve, correspomling to the cavity di, in the upsettingtool and hy the same movement, the horizontal spring-toothed arm t is caused to advance, and intel'- lock itself with one of' the teeth of the ratchet-wheel 12. At this moment, the vertical tool q is caused to descend, and coming in contact with the already sharply-curved end of the buckle-tongue, presses it downward, and completes the formation of the eye of the tongue around the bar of the buckle, as shown in fig. 8. v

The tools are then caused to recede simultaneously, while at the same moment, the spring-toothed hook t being also drawn back, causes the rotating head-block fr to revolve a suicient distance to carry the finished buckle out of the way, and present another' one in its stead in the line of `the upsetting-tool. At the same moment,the receding of the upsetting-tool causes the toothed detacher c' to approach the head-block Ir, and bythe action of the spring al, to carry the detaehingl tooth 13 overI the bar of the finished buckle, `so that whcnthe upsetting-tool again advances, the cam (l1 upon its closs-headystrikes against the shoulder g of the said toothed detaehing-arm, and imparts to it a place, as modifications of my invention, ofthe rotating head-block, in which case, a'siugle tongueis inserted in a fixed head-block, and\supported. against the ac- "tion of the upsetting-tool by means of an adjustable stop.`
